Synchronous multiple small adenocarcinomas are detected more frequently than in the past; however, the genetic profile, treatment, and prognosis of patients remain unclear. For treatment decisions and prognostic applications, we evaluated epidermal growth factor receptor (EGFR), p53, and KRAS somatic mutations in synchronous multiple small lung adenocarcinomas. ⋯ Whether these tumors are different or the same clonal, sublobar resection of each lesion can achieve long-term DFS and is the treatment of choice for synchronous multiple small lung adenocarcinomas. Patients with lymph node metastasis are at risk of relapse and adjuvant chemotherapy is indicated.

For patients with unresectable intrahepatic cholangiocarcinoma (ICC), treatment options are limited and survival is poor. This study summarizes the long-term outcome of two previously reported clinical trials using hepatic arterial infusion (HAI) with floxuridine and dexamethasone (with or without bevacizumab) in advanced ICC. ⋯ HAI chemotherapy can result in prolonged survival in unresectable ICC. Pre-HAI DCE-MRI may predict treatment outcome.

Comparative Study
What is the effect of laparoscopic colectomy on pattern of colon cancer recurrence? A propensity score and competing risk analysis compared with open colectomy.
Variability in colon cancer recurrence after laparoscopic colectomy (LAC) remains poorly understood. The aim of our study was to quantify the influence of LAC on colon cancer recurrence patterns. ⋯ Our study reveals that LAC and open colectomy demonstrate comparable overall colon cancer recurrence rates and recurrence sites. Specific clinicopathological characteristics may have a stronger influence on colon cancer recurrence site compared with the surgical technique.

This retrospective study aimed to determine prognostic factors associated with postrecurrence survival of completely resected non-small cell cancer patients with postoperative recurrence. ⋯ Poor ECOG PS, shorter time from initial surgery to recurrence, and increasing number of initial recurrent regions are associated with poor prognosis after recurrence. When the number of recurrent lesions is limited, intensive local treatment with curative intent should be applied for achieving long-term postrecurrence survival.

Recently, a simple and easy complication prediction system, the surgical apgar score (SAS) calculated by three intraoperative parameters (estimated blood loss, lowest mean arterial pressure, and lowest heart rate), has been proposed for general surgery. In this study, we evaluated the predictability of the original SAS (oSAS) for severe complications after gastrectomy. In addition, the predictability of a modified SAS (mSAS) was evaluated, in which the cutoff value for blood loss was slightly modified. ⋯ The oSAS was not found to be a predictive factor for severe complications following gastrectomy in Japanese patients. A slightly modified SAS (i.e. the mSAS) is considered to be a useful predictor for the development of severe complications in elective surgery.
